Audio issues with MacAir 2020

Hello,

Just got a new Mac (with the new M1 chip)-- and for some reason the audio and speakers do not work once I connect with someone -- even after having tested the audio and speakers. These work on both google meeets and streamyard-- so I reckon it really has something to do with connection to my zoom.

And the audio/ speaker only worked once-- when I tried using it with another friend who has a Mac. Very strange.

I have already tried uninstalling and reinstalling the Zoom app a few times.

Any other ways to fix this by any chance?

Thanks,

Joanna
